CARPET SWEEPER W 1TH BRUSH-CLEANING DEVICE.

Application filed October 26, 1922. Serial No. 597,053.

This invention relates to, an improved con struction of carpet sweeperwith brush cleaning device.

The objects of the invention are to provide a carpet'sweeper with abrush cleaning means coacting automatically therewith to keep the brushfree from lint, hair, thread and like debris.

A further object is to provide an improved construction of such deviceco-operating with the brush which shall be effective in collecting suchdbris from the brush and discharging the same into the dustpan.

Objects pertaining to details and economies of construction andoperation will definitely appear from the detailed descrip tion tofollow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification. The invention is 2 of thisapplication, in which:

Fig. I is a detail transverse sectional elevation View on line '1-1 ofFig. II, showing the brush, casing, floor wheels for driving the brush,and my improved automatic brush cleaner device disposed in position.

Fig. II is an enlarged detail transverse sectional elevation view online 22 of Fig. I, showing the relation of the brush to the cleanerteeth.

Fig. III is a detail perspective view of the toothed cleaner detached.

In the drawing similar reference characters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of the drawing, 1, 1 are the ends of thecase. 2 is the top or shell of the same. 3 is the brush, having separatetufts 4c, disposed in spiral relation as in well-known structures ofcarpet sweeper. 5 is the driven wheel of the brush, and 6, 6 are thefloor wheels engag ing to drive the carpet sweeper in any suitable way.

The brush is supported in the end bars 7 by suitable pivots and thestructure is pro vided with the usual furniture guard 8. 9 is the hail,of any suitable handle construction. 10 is the improved block or barwhich carries the improved toothed brush cleaner, the same being securedin place by screws 11 through the sides of the case. The toothed cleanerpart 12 is of sheet metal and provided with teeth 18 which are cut fromthe edge of the strip with curved points pointing alternately inopposite directions, as seen in Figs. II and III, the outwardly curvedpoints 13 being distinctly illustrated in both Figs. II and III. Thetoothed bar 12 is retained on the bar 10 by screws 14,see Figs. I andII. The teeth are of such length as to project slightly into theperiphery of the brush and are disposed in spaced relation so that theprojecting ends engage between the tufts at of the brush and thuseffectively pull or lift from the same any accumulations of string orhair or thread or other dbris. When the brush revolves toward one sidethese accumulations are naturally collected on the teeth at that sideand when the brush reverses its movement they are swung over anddeposited in the dustpan, seen at 15 in Fig. II.

The carpet sweeper is of course reciprocated back and forth on the floorand the teeth 13 at the opposite sides act alternately and effectivelyand immediately gather any dbris from the brush and discharge it intothe dustpan where it may be discharged from the sweeper in the usualway.

I have described my improved automatic carpet sweeper brush cleaningmeans in its approved form. I desire to state, however, that the teethmight be otherwise formed and otherwise supported, although at increasedexpense over the simple construction which I have shown. I thereforedesire to claim the same specifically as well as broadly, as pointed outin the appended claim.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

A sweeper for carpets or the like comprising a driven tufted brush and ametal comb strip secured to a longitudinal centrally-disposed barsecured to the casing of I the sweeper, which strip has outwardlythereof, and on the reversing of the brush discharge such debris intosuitable receptacles, substantiallyas described. 10

In Witness whereof, I have hereunto setmy hand. 7
